One use only. The banner can be activated at the beginning of any player's turn. Within 24" of the banner, no model may use the Fly special rule and units are at -2 to be Hit with non-magical missile attacks. All non-magical missile attacks that do not use Ballistics Skill to hit need to roll a 4+ on a D6 before they can attempt to fire if they are within 24" of the banner. Roll a D6 at the beginning of each following player turn - the effects of the banner will end on a D6 roll of 4+.
